gleam cant find elixir.app when using finch in a project.

Bamii commented 1 year ago

install finch: gleam add finch_gleam
import finch in the project. (you dont even need to use the library, just import it): import finch
run gleam run result: exception error: no match of right hand side value {error,{elixir,{"no such file or directory","elixir.app"}}}

command: elixir --version result:

Erlang/OTP 25 [erts-13.2] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit:ns]
Elixir 1.15.7 (compiled with Erlang/OTP 24)

command: gleam --version result: gleam 0.31.0

Hello! I'm having trouble reproducing this. Could you share more information please?

What operating system are you using? How did you install Gleam and Elixir? Could you share everything Gleam prints to the console after you run gleam run 🙏

Thank you

@lpil OS: Windows 11 Installed Gleam & Elixir using scoop

so, its even crazier because if i create a new project and just do these steps... it works fine. but on this one project i'm working on, it breaks. (and i just found out i don't need to import the library, mere installing it breaks the program)

gleam.toml

version = "0.1.0"
gleam = ">= 0.32.0"

[dependencies]
gleam_stdlib = "~> 0.31"
gleam_http = "~> 3.5"
gleam_json = "~> 0.6"
gleam_erlang = "~> 0.22"
gleam_hackney = "~> 1.1"
finch_gleam = "~> 4.0"

[dev-dependencies]
gleeunit = "~> 0.10"

sequence of events i took to reproduce:

PS C:\Users\ACER-PC\Documents\work\openai> gleam remove finch_gleam  // to make sure its uninstalled.

lpil commented 1 year ago

Very strange. Could you share what the openai module looks like?

Bamii commented 1 year ago

inside src/ all the files are empty... except

opeapi.gleam which contains the main function. (i tried emptying this file too, so that theres just a main function that prints out something, same error occured.)
api.gleam which contains some gleam/http/request builders and
chat.gleam which contains some functions..

fortunewang commented 12 months ago

I get the same issue when I run gleam run without Administrator terminal at first.

Create a hello-world project
Run gleam add floki (adds an Elixir dependency)
Run gleam run. This will fail by creating symbol link build/dev/erlang/eex without Administrator privilege. But build/dev/erlang/gleam_elixir_paths still exists as if build/dev/erlang/{eex, elixir, logger, mix} was successful created.
Open an Administrator terminal, run gleam run again. Symbol link build/dev/erlang/floki is created. Starting OTP application floki will fail because application elixir does not exist at build/dev/erlang/elixir.

To fix it, remove build/dev/erlang/gleam_elixir_paths, edit some source codes to force re-compiling.

lpil commented 11 months ago

Ah fantastic, that's really useful! Thank you so much!

lpil commented 11 months ago

Would you be able to test tomorrow with the nightly build please? 🙏

fortunewang commented 11 months ago

I don't know if @Bamii 's trouble was caused by the privilege issue, but the privilege issue isn't fix by 11146add8e63f51a9d82d463b91901528766b71f

The problem is, normal users cannot create symbol links on Windows. This limitation is introduced by system api CreateSymbolicLinkW.

Maybe we could remove build/{target}/erlang/gleam_elixir_paths if failed creating symbol links at https://github.com/gleam-lang/gleam/blob/11146add8e63f51a9d82d463b91901528766b71f/compiler-core/src/build/package_compiler.rs#L530 and warn the lacking of privilege on windows

Or append Elixir's ebin paths with -pa <ebin path> separately when gleam run, instead of creating their symbol links together with dependencies?

lpil commented 11 months ago

Oh I see! Sorry, I have misunderstood the problem. I thought the symlink operation was silently failing, but instead it was that it fails but the build tool did not clean up the directories as required.

Would you be able to show me what the error looks like?

Adding the Elixir ebin paths is a great idea! It's not trivial to implement that so I'll make an issue for it.

Thank you. Does using the nightly now result in the error happening every time gleam build is run without the elevated permissions?
